Eclogites and eclogites in the Besshi district, Sambagawa metamorphic belt, central Shikoku, southwest Japan-their similarity and variety-

Abstract

Three metamorphic events are distinguished in the eclogites occurring in the Besshi district, Sambagawa metamorphic belt, southwest Japan. They are, 1) precursor metamorphism before high P/T eclogitic metamorphism (granulite-amphibolite facies) , 2) multiple eclogite facies metamorphism, and 3) epidote amphibolite metamorphism. The eclogites in the Besshi district experienced some of these metamorphic events.
